Add an option to "demultilib"
It turns out buildroot does not currently accept a toolchain where a dynamic
linker does not reside in the multi-os-directory. Unfortunately this is
how glibc installs itself on AArch64 without any extra tricks.
So, provide an option to force everything into /lib or /usr/lib; patch to
buildroot will be worked on separately.
